Kodi chotenthetsera mufiriji chimagwira ntchito bwanji?

Nthawi zambiri, chowongolera kutentha cha firiji m'nyumba nthawi zambiri chimakhala ndi 0, 1, 2, 3, 4, 5, 6, ndi 7 malo.Kuchuluka kwa chiwerengerocho, kumachepetsa kutentha mufiriji.Nthawi zambiri, timayika mu giya lachitatu mu kasupe ndi autumn.Kuti tikwaniritse cholinga cha kusunga chakudya ndi kupulumutsa mphamvu, tikhoza kugunda 2 kapena 3 m'chilimwe ndi 4 kapena 5 m'nyengo yozizira.

Pogwiritsa ntchito firiji, nthawi yake yogwira ntchito komanso mphamvu zamagetsi zimakhudzidwa kwambiri ndi kutentha kozungulira.Choncho, tiyenera kusankha zida zosiyanasiyana kuti tigwiritse ntchito pa nyengo zosiyanasiyana.Zotenthetsera m'firiji ziyenera kuyatsidwa ndi zida zochepa m'chilimwe komanso nthawi yozizira kwambiri.Pamene kutentha kozungulira kuli kwakukulu m'chilimwe, kuyenera kugwiritsidwa ntchito muzitsulo zofooka 2 ndi 3. Pamene kutentha kozungulira kumakhala kochepa m'nyengo yozizira, kuyenera kugwiritsidwa ntchito muzitsulo zolimba 4,5.

Mwinamwake mukudabwa chifukwa chake kutentha kwa firiji kumakhala kokwera kwambiri m'chilimwe.Izi ndichifukwa choti m'chilimwe, kutentha kozungulira kumakhala kokwera (mpaka 30 ° C).Ngati kutentha mufiriji kuli mu chipika cholimba (4, 5), ndi pansi -18 ° C, ndipo kusiyana kwa kutentha pakati pa mkati ndi kunja ndi kwakukulu, kotero kumakhala kovuta kuchepetsa kutentha m'bokosi ndi 1. ° C. Komanso, kutayika kwa mpweya wozizira kupyolera mu kutsekemera kwa kabati ndi chisindikizo cha chitseko kudzafulumizitsidwanso, kotero kuti nthawi yayitali yoyambira ndi nthawi yochepa yochepetsetsa idzachititsa kuti compressor azithamanga kutentha kwa nthawi yaitali. , yomwe imadya mphamvu ndikuwononga mosavuta kompresa.Ngati atasinthidwa kukhala zida zofooka (2 ndi 3rd gear) panthawiyi, zidzapezeka kuti nthawi yoyambira imakhala yochepa kwambiri, ndipo kuvala kwa compressor kumachepetsedwa, ndipo moyo wautumiki umakulitsidwa.Choncho, kutentha kwa kutentha kudzasinthidwa kukhala kofooka pamene chilimwe chikutentha.

Kutentha kozungulira m'nyengo yozizira kumakhala kotsika, ngati musinthabe chotenthetsera kuti chikhale chofooka.Choncho, pamene kusiyana kwa kutentha pakati pa mkati ndi kunja kuli kochepa, kompresa sikudzakhala kosavuta kuyamba.Mafiriji okhala ndi firiji imodzi amathanso kusungunuka mufiriji.

Firiji wamba imagwiritsa ntchito chosinthira kutentha kuti firiji isamatenthe.Pansipa tikuwonetsani kuti tifotokoze mfundo yogwira ntchito yosinthira kutentha kwanthawi zonse.

Chophimba chosinthira kutentha ndi cam chimagwiritsidwa ntchito kukhazikitsa kutentha kwapakati pa firiji.Mu phukusi la kutentha lotsekedwa, "nthunzi yonyowa yonyowa" imakhala ndi gasi ndi madzi.Nthawi zambiri refrigerant ndi methane kapena freon, chifukwa kuwira kwawo kumakhala kocheperako, ndikosavuta kusungunuka ndikukulitsa mukatenthedwa.Chipewacho chimalumikizidwa ndi kapisozi kudzera mu chubu cha capillary.Kapsule iyi imapangidwa ndi zida zapadera ndipo imasinthasintha kwambiri.

Kulumikizana kwamagetsi kumayambiriro kwa lever sikutsekedwa.Kutentha kumakwera, nthunzi yochuluka mu paketi ya kutentha imakula ikatenthedwa, ndipo kuthamanga kumawonjezeka.Kupyolera mu kuthamanga kwa capillary, capsule imakulanso.

Potero, lever imakankhidwa motsatana ndi koloko kuti igonjetse torque yomwe imapangidwa ndi kugwedezeka kwa masika.Kutentha kukafika pamlingo wina, zolumikizira zimatsekedwa, ndipo kompresa ya firiji imayamba kugwira ntchito kuziziritsa.Kutentha kumachepa, mpweya wochuluka umachepa, kuthamanga kumachepa, zolumikizana zimatseguka, ndipo firiji imasiya.Kuzungulira kumeneku kumapangitsa kuti firiji ikhale yotentha kwambiri komanso imateteza magetsi.

Malinga ndi mfundo ya kukula matenthedwe ndi chidule cha zinthu.Kuwonjezeka kwa kutentha ndi kutsika kumakhala kofala ku zinthu, koma mlingo wa kukula kwa kutentha ndi kutsika kumasiyana kuchokera ku chinthu ndi chinthu.Mbali ziwiri za pepala lagolide wapawiri ndi ma conductor a zinthu zosiyanasiyana, ndipo pepala lagolide lawiri limapindika chifukwa cha kukula ndi kutsika kosiyanasiyana pa kutentha kosiyanasiyana, ndipo kukhudzana kapena kusinthana kumapangidwa kuti ayambe kuzungulira (chitetezo) ntchito.

Masiku ano, mafiriji ambiri amagwiritsa ntchito machubu ozindikira kutentha kuti azindikire kutentha.Madzi omwe ali mkati mwake amakhala ndi madzi, omwe amakula ndikulumikizana ndi kutentha, amakankhira chidutswa chachitsulo kumapeto kwake, ndikuyatsa ndi kuzima kompresa.
